  The Small knot or Oriental knot is a simple yet lesser known thin tie knot. This knot will not self release, thereby being unfavorable for those who get hot under the collar. It's a symmetric knot which gets bigger as the tie gets thicker. These tie knots work best with loom ties or silk knit narrow ties.

The Half Windsor knot is larger than the Four-in-Hand knot and works best with light and medium weight fabrics. The Half Windsor knot is one of the most well known tie knots in the world, see A Gentleman Gets Dressed Up: What to Wear, When to Wear it, How to Wear it. It's a symmetric medium sized tie knot with the figure of a perfect triangle. I've embedded a Half Windsor how to video below or you can view it here.
